Hi Ronn--

A similar question to this was asked a few months ago.  No really deep
technical discussions ensued, but this was the gist of it:

* I advocated astronomy's FITS format.  Plus: platform independent,
  metadata is in ASCII, good support in IDL Astronomy Library.  Minus:
  seen as "archane."

* I also advocated IDL SAVE files.  With my library you can read and
  write SAVE files sequentially like any other file.  Plus: native to
  IDL. Minus: tied to IDL.

* Many people seem to swear by Liam Gumley's binary tools.  Plus: raw
  speed and direct access; platform neutral. Minus: low level.

* Martin Schultz advocated GRIB, half tongue in cheek.

As I said, no real answers came out of this, but at least it may give
you some other ideas.
